Answer:
6. x = 3
8. x = -7.5
Step-by-step explanation:
Put the number in place of the expression it is equal to, then solve for x.
__
6) g(x) = -x +5
2 = -x +5 . . . . . . . . . g(x) is replaced by 2, because g(x) = 2
x +2 = 5 . . . . . . . . . . add x to both sides
x = 3 . . . . . . . . . . . . . subtract 2 from both sides
__
8) n(x) = -2x -21
-6 = -2x -21 . . . . . n(x) is replaced by its equal: -6
3 = x +10.5 . . . . . . divide both sides by -2
-7.5 = x . . . . . . . . . subtract 10.5 from both sides

<em>Additional comment</em>
We have shown a couple of ways these equations can be solved. You can separate the x-term and the constant terms before you divide by the x-coefficient, or you can do it after. In the first equation, we could have solved it ...
2 -x +5
-3 = -x . . . . subtract 5
3 = x . . . . . . multiply by -1
The way we did it avoids negative numbers.
Answer:
the y intercept is 2
Step-by-step explanation:
we can see this because the line crossed the 2 on the y axis line
The expression represents the number of packages of mulch that will be needed to cover both rounded ends is 600/x
<h3>How to determine the
expression represents the
number of packages of
mulch that will be needed to cover both rounded ends?</h3>
The given parameters are:
Area covered = 300 square feet
Number of ends = 2
So, the total surface area is:
Total surface area = Area covered * Number of ends
This gives
Total surface area = 300 * 2
Total surface area = 600 square feet
Let the area covered by each package of mulch be x.
So, the number of mulch is
Number = Area covered/area covered by each
This gives
Number = 600/x
Hence, the expression represents the number of packages of mulch that will be needed to cover both rounded ends is 600/x
